H. PUSH START BUTTON
The timer starts. The On lamp and the red
LED on the timer illuminate. The voltmeter
displays the battery terminal voltage and the
ammeter reads zero..
I. SET CHARGE CURRENT
1. FOR CONSTANT-CURRENT
CHARGING
Turn the Ampere Adjust knob until the
desired charge current has been reached.
The charge current is displayed on the
ammeter as the current is being adjusted.
2. FOR CONSTANT-POTENTIAL
CHARGING
Turn the Ampere Adjust knob to max (fully
clockwise) or to the desired current limit. The
charge current is displayed on the ammeter
as the current is being adjusted.
J. WAIT FOR THE CHARGE TO AUTOMATICALLY
COMPLETE
During the charging of the battery the battery voltage, charge current, and
elapsed charge time are displayed.
•
For the constant-current method the current remains constant while
the voltage increases during the time of charging.
•
For the constant-potential method the charger’s end voltage remains
constant while the current starts at a high value and gradually
approaches zero as the battery approaches a full charge.
The actual charge voltage is determined by the battery, until the constant
voltage is reached (14.7 volts, 28.5 volts or 35 volts in constant-current
